Heliostats, movable mirrors, were used to concentrate the sun's rays on a central tower of initially water, and later, salt.
Solar One and Solar Two were test sites, and neither operates anymore. The array of mirrors has been converted to be part of a gamma ray telescope (the mirrors now focus the brief and very weak flashes of light generated by cosmic gamma rays as they enter the earth's atmosphere onto a detector).
Another plant, Solar Tres, (later Gemasolar) was built in Spain, using the technology of Solar One and Solar Two, and three times bigger. Its molten salt storage means it can run during 15 hours of darkness. During the summer of 2013 the plant ran 24/7 for 36 consecutive days.

Another names for solar rays is UV rays.
The heat facouses all the rays back into the light this is how solar ovens focus the sun rays
Ultraviolet rays are generally considered a harmful disadvantage of solar energy. These rays cause damage to the solar panels over an extended period of time.
light rays
They contain more solar energy!
the energy from the suns rays enters the solar panels
Depending on whether it's a convex or concave lens - Either concentrate the rays to a point - or diverge them to infinity !
solar flares appear as a dark spot
there is always going to be wind and solar rays
"The solar rays are hotter on the equator than in the northern hemisphere."
